False. They are values from different objects. Just make __eq__ map to
"is". I think you'll be fine.
Ben> Or is it an error to even try comparing them?
As someone else pointed out containment tests become difficult with your
current formulation.

I think so. <0.5 wink>. I think you should be able to compare any two
objects. I think the complex types give you a little wiggle room on the
size comparisons (<, <=, >, >=), but I think == and != really ought to work.
